Throttle Position (TP) Sensor

The TP sensor monitors throttle plate opening. Its signal to the ECA is proportional to opening angle. It is mounted on the throttle body at throttle plate rod. The TP signal affects air/fuel ratio, injector timing, idle speed, EGR flow, fuel pressure, and ignition timing (turbo engine).
